  • Description: The problem of runaway smelt explosions due to a sudden influx of smelt into a dissolving tank is mitigated by a system comprising a dissolving tank (135); a spout (105) adjacent to the dissolving tank (135), wherein the spout is configured to convey a volume of smelt (110) into the dissolving tank (135); an agitator (140) disposed in the dissolving tank (135), wherein the agitator (140) is configured to mix the volume of smelt (110) into a dissolving liquid (130) in the dissolving tank (135); and an ultrasonic transducer (150) configured to emit ultrasonic waves (153) within the dissolving tank (135) at a frequency above 20 kilohertz. A system comprising the ultrasonic transducer may further comprise sensors and a data processor configured to regulate the properties of the ultrasonic waves in response to process conditions affecting the smelt flow.
